* NEWS: doc: update NEWS for 2.6.3 release
2016-11-26 Explorer09 <explorer09@gmail.com>
* configure.ac, src/Makefile.am: build: New configure option
'--disable-bootstrap'. If configure is run with '--disable-bootstrap', then stage1flex
won't be built and stage1scan.c will be generated by sed'ing scan.c. This option is intended to workaround bootstrap bugs rather than to
fix the bootstrapping issues which are proving subtler and harder to
fix than anyone would like.
2016-11-26 Explorer09 <explorer09@gmail.com>
* src/Makefile.am: build: "make clean" deletes stage1scan.c,
stage1flex
2016-11-26 Explorer09 <explorer09@gmail.com>
* configure.ac, src/Makefile.am: build: allow building libfl even
with --disable-libfl. For various reasons, we may wish to build libfl explicitly even when
configure has been run with the --disable-libfl option. This is
possible, now, via 'make -C src libfl.la'.
2016-12-19 Alexis La Goutte <alexis.lagoutte@gmail.com>
* src/flex.skl: scanner: remove trailing whitespace in skeleton
2016-12-01 Demi Obenour <demiobenour@gmail.com>
* src/buf.c, src/main.c, src/parse.y: scanner: Disallow, overquote
'[' and ']' in prefix
2016-12-29 Samuel Thibault <samuel.thibault@ens-lyon.org>
* src/main.c: scanner: allocate correct buffer size for m4 path. Flex did not check the length of the m4 path which could lead to a
buffer overflow in some cases. Additionally, not all platforms
believe in PATH_MAX, so stop relying on it. Fixes#138
2016-11-24 Will Estes <westes575@gmail.com>
* NEWS: doc: note no more libcompat in NEWS
2016-11-24 Will Estes <westes575@gmail.com>
* lib/Makefile.am: build: explain empty lib/Makefile.am
2016-11-20 Explorer09 <explorer09@gmail.com>
* configure.ac: build: warn about cross compiling with *alloc
2016-11-19 Explorer09 <explorer09@gmail.com>
* configure.ac, lib/Makefile.am, lib/lib.c, src/Makefile.am: build:
Link $(LIBOBJS) from src/ dir, remove libcompat.la. The libcompat.la library was small and less friendly to
bootstrapping and cross compilation. Now, we will simply link
individual object files as needed, which is simpler.
2016-11-16 Explorer09 <explorer09@gmail.com>
* src/Makefile.am: build: Let stage1flex respect LFLAGS
2016-11-14 Will Estes <westes575@gmail.com>
* NEWS: doc: describe --disable-libfl in NEWS
2016-10-31 Explorer09 <explorer09@gmail.com>
* configure.ac, src/Makefile.am: build: Add --disable-libfl
configure option. Disabling libfl is useful when building flex for a cross-toolchain. Fixes: GH-99
2016-11-09 Demi Obenour <demiobenour@gmail.com>
* src/flex.skl, tests/array_r.l: fix backwards incompatible changes
in 2.6.2. This patch addscompatibility `#defines` for all macros affected by
`%prefix`. Fixes#113.
2016-11-08 Will Estes <westes575@gmail.com>
* tests/.gitignore: git: ignore quote_in_comment artifacts
2016-11-08 Demi Obenour <demiobenour@gmail.com>
* src/scan.l, tests/Makefile.am, tests/quote_in_comment.l,
tests/quote_in_comment.txt: Fixes a major bug in Flex's own lexing
of literals. My changes caused Flex to mishandle string and character literals in
line comments. This commit fixes them. Fixes#113.
2016-11-06 Thomas Klausner <wiz@NetBSD.org>
* configure.ac: Fix unportable test(1) operator. "==" is only supported by bash, "=" is the standard comparison
operator.
2016-11-02 Demi Obenour <demiobenour@gmail.com>
* tests/quotes.l: Add more escaping tests
2016-11-01 Demi Obenour <demiobenour@gmail.com>
* src/scan.l: Fix another escaping bug in non-indented verbatim section 2 code. I also did some reformatting.
2016-10-28 Alastair Hughes <hobbitalastair@gmail.com>
* configure.ac: build: fix false negatives for help2man and texi2dvi HELP2MAN and TEXI2DVI (or the corresponding ac_prog variables) will
never be zero length as they fall back to the missing script; check
for the fall back and warn on that instead of always warning.
2016-10-28 Explorer09 <explorer09@gmail.com>
* doc/Makefile.am: doc: Don't delete flex.1 during "make distclean". flex.1 is pre-generated in release tarball. If we delete it, the
next "configure and make" on the source directory will then require
help2man unnecessarily.
2016-10-27 Alastair Hughes <hobbitalastair@gmail.com>
* NEWS, doc/Makefile.am: Only regenerate the man page when required. Make the flex binary an order-only prerequisite, and add back the
prerequisites from before 7cfb440. This prevents rebuilding the man
page whenever the flex binary is rebuilt, which causes problems if
help2man is not installed and will never work when cross compiling. Fixes#108.
2016-10-26 Will Estes <westes575@gmail.com>
* NEWS, src/Makefile.am: build: no longer build PIC version of
libfl. The PIC version of libfl was not being built correctly. From the
lack of bug reports around this problem, we conclude that the PIC
version of libfl is not used and so we drop it from the build build
targets for flex.
2016-10-25 Explorer09 <explorer09@gmail.com>
* README.md: doc: README.md formatting fixes * Wrap everything in the raw document in 72 char per line limit. * Proper casing for terms "Git" and "GitHub" (don't try to look
lazy). * Add unordered list marks when needed. * Say `configure && make && make install` and quoted for fixed-width font. Signed-off-by: Kang-Che Sung <explorer09@gmail.com>

src/scan.l, tests/bison_yylval_scanner.l,
tests/include_by_push.direct.l: Improved M4 quotation This fixes M4 quotation of certain strings beginning with `yy` (in
section 3 of the input file only) and character literals. The new
quotation method is also less brittle and faster. Tests that relied on the old behavior were fixed. Also, `yyconst` is no longer defined; use `const` (which it
unconditionally was defined to) instead.
2016-10-19 Will Estes <westes575@gmail.com>

escape sequences and character constants. Tests were added to verify the behavior in section 3 with respect to
quoting. Both escaping of quotes and quoting of potential
macro-start characters are tested. Existing tests were also fixed to
account for the new -- and now correct -- behavior. Many tests
relied on the old behavior of expanding M4 macros in section 3.
They needed to be updated for the new behavior.

* src/scan.l: Fix escaping of `[[` and `]]` in strings Previously, `[[` and `]]` were not escaped in strings, which led to
bad interactions with m4. Also, don't break strings on newline, as GCC et al support
whitespace between a backslash and the subsequent newline.

2016-04-28 Tobias Klauser <tklauser@distanz.ch>
* src/scanflags.c: Avoid realloc on every call of sf_push() Currently, every call to sf_push() realloc()'s _sf_stack, even if
the maximum size _sf_max wasn't changed. As the indentation beneath
the "if" clause already indicates, the realloc() should only be
executed if _sf_max was increased. Found by compiling flex with the -Wmisleading-indentation flags of
gcc, which leads to the following warning: scanflags.c: In function âsf_pushâ: scanflags.c:42:5: warning:
this âifâ clause does not guard... [-Wmisleading-indentation] if
(_sf_top_ix + 1 >= _sf_max) ^~ scanflags.c:44:9: note: ...this
statement, but the latter is misleadingly indented as if it is

2016-02-24 Will Estes <westes575@gmail.com>
* src/flex.skl: Changed type of yy_n_chars to int; gh#53, sf#160. The variable yy_n_chars had been of type yy_size_t which is
incorrect given its use in read(). While it might be adviseable to
look at defining a yy_ssize_t, there might be some issues doing this
and so, for now, at least, we'll punt back to int.
2016-02-24 Will Estes <westes575@gmail.com>
* src/buf.c: Fixed size of bufferallocation, resolved gh#54. The value of n_alloc was a count, not a size. Multiplying the value
by the element size was incorrect. That multiplication was already
being done and having it done twice was incorrect.

* src/scan.l: Allow '%option noline' in flex input file, resolves

* src/buf.c, src/main.c: Emit no #line directives if gen_line_dirs

gen_line_dirs. Fix them, so they also respect gen_line_dirs. Signed-off-by: Tobias Klauser <tklauser@distanz.ch>

* lib/lib.c, src/gen.c, src/misc.c, src/scan.l: Converted K&R style
function definitions to ANSI C style Consistently make use of the ANSI C function definition style
instead of the K&R style.
2016-01-29 Tobias Klauser <tklauser@distanz.ch>
* src/flex.skl: Used NULL constant instead of plain integer for NULL
pointer. The sparse static checker warns about using plain integer 0 as NULL
pointers in the generated lexer code. Fix this by using NULL
consistently for pointers.
2016-01-29 Tobias Klauser <tklauser@distanz.ch>
* src/flex.skl: Marked declaration and definition of yy_fatal_error
as noreturn. Only the declaration of yy_fatal_error is marked with
__attribute__((__noreturn__)) in case GCC >= 3 is used, but not the
definition. This leads to the sparse static checker to complain
about function declaration mismatch. Fix it by defining a macro yynoreturn and using it for both the
declaration and the definition of yy_fatal_error.
2016-01-27 Tobias Klauser <tklauser@distanz.ch>
* src/flex.skl: Fixed declaration mismatch in yy_fatal_error. The prototype declares yy_fatal_error parameter as "const char
msg[]" while the definition uses "const char* msg" (introduced by
commit e9d5fc713f61b) which causes the sparse static checkers to
produce an error. Fix this by adjusting the definition to use "const char* msg" as
well. Also change the C++ version accordingly so it matches the
declaration in FlexLexer.hpp.

2015-12-27 Will Estes <westes575@gmail.com>
* src/flexdef.h, src/main.c: include libgen.h from flexdef.h, not
main.c
2015-12-25 Michael Reed <m.reed@mykolab.com>
* src/main.c: Replace basename2() with basename(3). Given the following program: \#include <libgen.h> \#include <stdio.h> /* extracts basename from path, optionally stripping the extension
"\.*" * (same concept as /bin/sh `basename`, but different handling
of extension). */ static char *basename2 (char *path) { char *b; for (b = path; *path; path++) if (*path == '/') b = path + 1; return b; } static void basename_compare(char *path) { printf("basename: %s\n", basename(path)); printf("basename2: %s\n\n", basename2(path)); } int main (int argc, char *argv[]) { // From http://pubs.opengroup.org/onlinepubs/9699919799/ // ``Sample Input and Output Strings'' basename_compare("/usr/lib"); basename_compare("/usr/"); basename_compare("/"); basename_compare("///"); basename_compare("//usr//lib//"); return 0; } ... and the program's output: basename: lib basename2: lib basename: usr basename2: basename: / basename2: basename: / basename2: basename: lib basename2: ... we can see that basename2() behaves the same as basename(3) in
the average use case, but messes up pretty severely in others.
Besides that, basename(3) is mandated by POSIX so should be present
on modern Unix-like systems, so we shouldn't define it ourselves. Some notes: - it doesn't appear to be mentioned in POSIX, but OpenBSD's
basename(3) returns NULL if the returned path componenet is >
PATH_MAX, so add a check for that - basename(3) shouldn't return an empty string, so remove the program_name[0] != '\0' check
2015-12-25 Michael Reed <m.reed@mykolab.com>
* src/main.c: Simplify basename2(). It's only call site does not activate the `strip_ext` code path, so
the function can be simplified a lot. While here, remove a double
assignment.
2015-12-25 Michael Reed <m.reed@mykolab.com>
* src/flex.skl, src/misc.c: Cleaned up __STDC__ #ifdefs. Assuming a compiler conforming to the ISO C standard is used, i.e.,

eliminated.

* src/gen.c, to.do/unicode/gen.c: Removed macros for indentation
level. Just increment or decrement the indentation counter. That's less to
remember and makes the code more readable. w# Please enter the commit message for your changes. Lines starting
2015-12-12 Mike Frysinger <vapier@gentoo.org>
* tests/Makefile.am, tests/testwrapper.sh: tests: fixed paths to
input files. The current test wrapper works only when the inputs are specified
using relative paths. If they're specified with absolute paths, the
driver fails to detect the inputs because it always prepends the
input dir name which itself is a relative path: $ cd tests $
./testwrapper.sh -d . -i $PWD/reject.txt -t ./reject_ver.table
<fails to open inputs> This normally doesn't show up because people run `./configure` or,
for out of tree builds, `../configure`. But if you happen to run
configure with an absolute path, then automake tends to generate
absolute paths as well leading to test failures. Fix all of this by dropping the implicit input directory prepending. - INPUT_NAME is often a list of files, not just a single one - the input directory is used to find the testname tables which are usually generated, so it's impossible to use files from both
source and build directories - most of the time, the full/correct path is already specified
2015-12-12 Mike Frysinger <vapier@gentoo.org>
* configure.ac: configure: fixed realloc test. The [] characters are used for quoting in m4, so the attempt to use
them in place of `test` fails yielding the warning at build time: .../flex/configure: line 20222: no: command not found
2015-12-12 Michael McConville <mmcco@mykolab.com>
* src/flexdef.h: Started removal of PROTO macro. The PROTO macro is no longer needed. Additionally, its usage is
inconsistent, so we began removing it.
2015-12-12 Michael Reed <m.reed@mykolab.com>
* Makefile.am, src/main.c: Removed SHORT_FILE_NAMES preprocessor
symbol. As a relic of MS-DOS, we don't need this. It's never defined; see 13b5b214f53d1c3354a7ab910bd160c126df1331. Removed additional MSDOS ifdef.
2015-12-11 Michael McConville <mmcco@mykolab.com>
* configure.ac, lib/reallocarray.c, src/flexdef.h: Added new
function reallocarray. This is taken from OpenSSH Portable, which in turn takes it from
OpenBSD. reallocarray wraps the stdlib's realloc function. It takes two size
arguments and checks for overflow, like calloc, but doesn't zero the
memory. Therefore, it allows us to do overflow-safe array
reallocations and overflow-safe unzeroed array allocations, which
the stdlib allocation functions don't. We have a bunch of specific array allocation macros, none of which
check for overflow. reallocarray should be able to replace them.
2015-12-11 Michael McConville <mmcco@mykolab.com>
* src/flexdef.h: Removed MS-DOS, VMS macros. Given the age of the MS-DOS and VMS platforms, it's likely that no
one is building flex on them any more. Additionally, the preferred
approach is to test for particular platform features rather than to
test for particular platforms.

2015-12-09 Michael McConville <mmcconville@mykolab.com>
* src/flexdef.h: Removed implementation of isascii(). POSIX defines isascii(), so it's likely present on anything
weactually build flex on these days.

* src/main.c, src/scanopt.c, src/tables.c: Removed NULL-checks

* src/buf.c, src/dfa.c, src/flexdef.h, src/gen.c, src/scan.l,
to.do/unicode/flexdef.h, to.do/unicode/scan.l: Removed flex_free()i,
corrected buf_destroy logic. As with flex_alloc(), replace with direct calls to free(). The function buf_destroy is now null safe and the logic was
corrected to free() correctly.

src/scanflags.c, to.do/unicode/flexdef.h, to.do/unicode/misc.c,
to.do/unicode/scan.l: Removed flex_realloc(). As with flex_alloc(), replace calls to flex_realloc(), which was
just a wrapper around realloc().
2015-12-08 Michael McConville <mmcconville@mykolab.com>
* src/buf.c, src/filter.c, src/flexdef.h, src/main.c, src/misc.c,
src/regex.c, src/scan.l, src/scanflags.c, src/sym.c,
to.do/unicode/flexdef.h, to.do/unicode/misc.c, to.do/unicode/scan.l:
Removed flex_alloc; cleaned up style. The function flex_alloc() was just a wrapper around malloc(). Since
this only added unclarity, and the flex_alloc() function is likely a
legacy of olden times, remove it in favor of calls to malloc()
directly. Style elements cleaned up: * superfluous spacing around parentheses * non-constant initialization in variable declarations * needless casts * almost all uses of assignments as subexpressions

2015-12-07 Will Estes <westes575@gmail.com>
* src/.gitignore, src/Makefile.am: Built flex with itself. Changes in scan.l need to be built into flex with the same version
of flex in some cases. Since this build requirement is minimal, we
simply bootstrap flex unconditionally. We intentionally exclude from version control the bootstrap
artifacts as the extra copy of the lexer, the intermediate scanner
and the bootstrap executable are not of interest.

src/scan.l, src/scanopt.c, src/sym.c, to.do/unicode/main.c,
to.do/unicode/scan.l: Use NULL rather than (type *) 0.

* src/flexdef.h, src/misc.c, src/sym.c, to.do/unicode/flexdef.h,
to.do/unicode/misc.c: Replace copy_unsigned_string() with xstrdup(). Like copy_string(), copy_unsigned_string() is just a clone of the
stlib's strdup(). We only use it twice. I'm pretty confident that
char signedness is irrelevant in this case.
2015-12-04 Akim Demaille <akim@lrde.epita.fr>
* src/FlexLexer.h: Cleaned up white space.
2015-12-04 Akim Demaille <akim@lrde.epita.fr>

2015-12-04 Akim Demaille <akim@lrde.epita.fr>
* examples/testxxLexer.l, src/FlexLexer.h, src/flex.skl, src/main.c:
Replaced FLEX_STD macro with std::. The std:: construct exists as of C++98, so we can simply assume it
is supported.
2015-12-04 Akim Demaille <akim@lrde.epita.fr>
* src/Makefile.am: Generated skel.c explicitly in srcdir. Rewrote the target for skel.c to explicitly mention the srcdir. This
should help when building flex from a directory outside the flex
tree. Spread the rule out over several lines to enhance readability.
2015-12-04 Akim Demaille <akim@lrde.epita.fr>
* autogen.sh: Called glibtoolize if libtoolize run fails. On Mac OS X, libtoolize is known as glibtoolize. In cases where
libtoolize is not present, then calling glibtoolize when
bootstrapping the build system gives more folks a shot at getting
flex built from the ground up.
2015-12-02 Mightyjo <mightyjo@gmail.com>
* configure.ac: Checked for (g)texi2dvi. Better bison, help2man
checks. Added test for presence of (g)texi2dvi program. Gave notice if
texi2dvi is unavailable and set TEXI2DVI=: to avoid giving users
headaches. Enhanced tests for bison and help2man with notices when the programs
aren't found. Set their program variables to use the missing script
in build-aux since it's compatible with them.

src/tables.c, to.do/unicode/flexdef.h, to.do/unicode/misc.c,
to.do/unicode/scan.l: Made string copying more standard. copy_string() was a clone of the stdlib's strdup(). For safety,
simplicity, and speed, we should use that instead. We introduce
xstrdup() which wraps strdup() in a failure upon memory allocation
errors.

* src/ecs.c, src/flexdef.h, src/main.c, src/misc.c, src/scan.l,
src/scanopt.c, src/sym.c, src/tblcmp.c: Replaced CHAR macro with
unsigned char type. Thanks to Michael McConville for pointing out that the old Char
macro causes problems with static analysis. The macro has been
removed and replaced with 'unsigned char' throughout the flex
sources. The macro is not needed at best and was confusing at worst.
It was not used in any of the example files nor was it mentioned in
the manual at all.

while this is mostly a change to be consistent in style (the rest of the

we have an initial case to deal with a fairly common case: getting

checking if the real part is negative.
later, -0.0 < 0 is not met, so instead, test for a negative number
